Subheadings
Products classified under HTS 7608.20.00
6061 Aluminum Alloy Round Tube
Seamless round tubing made from 6061 aluminum alloy, commonly used in structural applications like frames and supports. It falls under HTS 7608.20.00 as it is a tube of aluminum alloys, where aluminum predominates but alloying elements like magnesium and silicon exceed non-alloyed limits. Typical outer diameter ranges from 0.5 to 6 inches with wall thicknesses from 0.035 to 0.5 inches.
6063 Aluminum Alloy Square Tubing
Extruded square profile tubing from 6063 aluminum alloy, ideal for architectural frameworks and railings. Classified under HTS 7608.20.00 due to its aluminum alloy composition with silicon and magnesium additions exceeding purity limits. Standard sizes include 1x1 to 4x4 inch profiles with 0.125-inch wall thickness.
5083 Aluminum Alloy Seamless Pipe
Seamless pipe from marine-grade 5083 aluminum alloy, used in shipbuilding and chemical processing. HTS 7608.20.00 applies as it's an aluminum alloy tube/pipe with magnesium content creating alloy properties per chapter definitions. Available in schedules 10/40/80 with diameters up to 12 inches.
7075 Aluminum Alloy Thin-Wall Tube
High-strength thin-wall tubing from 7075 aluminum alloy for aerospace and bicycle frame applications. Falls under HTS 7608.20.00 as aircraft-quality aluminum alloy tubing with zinc/copper/magnesium alloying. Wall thicknesses typically 0.028-0.065 inches for 1-2 inch OD.
3003 Aluminum Alloy HVAC Tubing
Coiled or straight 3003 aluminum alloy tubing for HVAC refrigerant lines and condenser coils. Classified HTS 7608.20.00 as aluminum alloy tubes containing manganese alloying elements. Common diameters 3/8" to 7/8" with 0.020-0.032" walls.
6061 Aluminum Alloy Telescopic Tube
Anodized telescoping tube sets from 6061-T6 alloy for antenna masts and flagpoles. HTS 7608.20.00 covers these aluminum alloy tubes designed for adjustable length applications. Sequential diameters allow 3-6 sections to extend/retract smoothly.
5052 Aluminum Alloy Hydraulic Cylinder Tube
Precision-bored 5052 aluminum alloy tubing for hydraulic and pneumatic cylinders. Falls under HTS 7608.20.00 as alloy tubes with magnesium content for marine hydraulic applications. Honed interior finish provides leak-free piston operation.
Extruded 6063 Aluminum Alloy Fence Rail Tubing
Extruded 6063 alloy tubing for aluminum fence rails and pickets in residential/commercial fencing. HTS 7608.20.00 classification for aluminum alloy tubes with architectural anodized finishes. Standard 2x2", 2.5x2.5" profiles with .090-.125" walls.
1100 Aluminum Alloy Drawn Tube
Precision drawn tubing from 1100 series aluminum alloy for instrumentation. Actually classifies in 7608.20.00 as commercial 'alloy' despite high purity due to processing. Ultra-smooth ID/OD for pneumatic controls and laboratory use.
Marine 5086 Aluminum Alloy Pipe
5086-H116 aluminum alloy pipe for seawater piping systems and boat hull thru-hulls. HTS 7608.20.00 for marine-grade alloy pipes with magnesium alloying for corrosion resistance. Meets MIL-DTL-15024 standards for naval applications.
